MECHANICAL MOVEMENT.

To all whom it may concern.-

Be it known that I, JAMES F. HANLEY, of Charleston, in the county ofCharleston and State of South Carolina, have invented a new and usefulImprovement in Mechanical Movements, of which the following is aspecification.

The object of my invention is to form compound double-crank rotarymotion with one lever, adapted for converting motion or connectingshafting; and itconsists in the peculiar construction and arrangementofp'arts claims.

Figure 1 is a side elevation, partly in section. Fig. 2 is an end view,partly in transverse section; and Figs. 3 and 4. are similar views of amodification.

A is a yoke-shaped frame, which has upon itsinner sides circular hubs orbosses a, through which pass the journals of-a double crank-shaft, B,having two cranks, b b, set diametrically opposite each other. Upon thehubs or bosses at are hung the forked ends of a hand or power lever, O.This operatinglever is connected by a fulcrum-pin, c, to the middle of apair of link-bars, D, which latter at their ends are jointed to the endsof curved semicircular levers E E, one of which, E, is fulcrumed to theframe A on one side of the crank-shaft, and the other of which, E, isfulcrnmed to the frame on the oth'erside of the shaft, and which leverscurve around the said shaft. The ends of theselevers opposite thelink-bars D are separately connected by pitman-rods 'F F to the twocranks b b of the crankshaft.

When an oscillating motion is given to the operating-lever C, it turnson the hubs or bosses a of the frame as a center, and through thelink-bars D it transmits a reverse motion to the two curved levers E E,which causes the pitmen on the opposite ends of the same to work inunison on the oppositelyset cranks of the crank-shafts, causing onepitman to pull in one direction while the other is push- .ing in theopposite direction to give a continuous rotary motion, which may be madesteady by a fly-wheel.

My device is simple in every detail, and, while giving the doubleapplication of power, nearly two-thirds of the revolution is formed withone vibration of the reciprocating lever, enabling it to be applied toevery use for which a rotary motion is needed. There is no lost motion,but the power is directed to the cranks with each vibration of the leverand gives a backward and forward motion with the same ease. Whennecessary to use two levers on the one shaft, the double cranks on saidshaft are placed'at right angles to each other, thus completelyovercoming dead-center and giving the double application of power toevery quarter of a revolution the shaft makes. Every portion of itsworking parts is attached to its own frame at an equal distance from thecenter, making it of uniform leverage and evenly balanced in everyparticular.

As a modification of my invention I may form the operating-lever G inone piece with one of the semicircular levers, E, as in Figs. 3 and 4,the other parts remaining substantially the same.

Having thus described my invention,-whatI claim asnew is- 1. Thecombination, with a frame, A, ofa crank shaft, B, having twooppositely-set cranks, b b, semicircular levers E E, fulcrumed in theframe upon opposite sides of the crankshaft and curving around thelatter, and a pair of pitmen connecting one pair of ends of the le- Versto the cranks, the other ends of said levers being connected together bya link onthe opposite side of the crankshaft, and provided with anextended operating-lever, as described.

2. The combination of frame A, having hubs or bosses at and crank-shaft13 passing through them, the operating-lever O, swiveling on said hubs,the semicircular levers E E, fulcrumed in the frame, pitmen F F,connecting levers E E to the cranks, and link-bars D, connecting thesemicircular levers and operating-lever, substantially as shown anddescribed.
